TectoWave is an independent Android app that shows public earthquake data from USGS, EMSC and GEOFON and tsunami bulletins from NOAA. It has no backend: each installed copy reads the public feeds directly.

For data-source operators

Requests from the app carry the User-Agent TectoWave/<version> (https://k41r05-a.github.io/tectowave-legal/contact/). Each installation checks the feeds in the background about every 15 minutes (Android may run the check less often; after a failed check the app retries up to three times, 5, 10 and 15 minutes apart), and again when the user opens or refreshes the feed: USGS all_day.geojson, the EMSC FDSN event service, the GEOFON event list and the NOAA PTWC and NTWC Atom feeds. If this traffic causes a problem, write to us and we will change the app in its next release.
